AWS Elastic Beanstalk Cluster Mode: Run Multiple Apps on Shared Infrastructure

AWS Elastic Beanstalk now lets you deploy multiple applications on pooled infrastructure using the new Cluster Mode, powered by Amazon EKS, which can significantly cut per-app compute costs as you scale. The feature supports event-driven autoscaling, OpenTelemetry observability, Secrets Manager integration, and HTTPS by default—available across all commercial AWS Regions with no extra charges beyond the resources you consume.
